I have twenty layin hens about 1 1/2 years old. I fill a 5 gallon water bottle inverted from a hanger for feeding besides any treats. (boss, scratch, etc) On occasion, they will empty this container by the following day, scattering plenty of feed. I wait until they clean this up prior to refilling it again. Does anyone feed thier flock as much as they want, or do you ration feed? My feed costs seem excessive. Anytime I approach thier pen, they all act as if Santa just arrived.
